That would be wonderful. They would need to make the Change-Over because of the plethora of battery platforms available. I can see them being quite expensive though. Lots of labour to test and refactor that many cells by hand. Consumed cells will need to be recycled and specialist technicians trained and experienced in working with high voltages will need to do the battery swaps in and out of vehicles.

One other good benefit would be that vehicles that are no longer roadworthy will be taken off the road. If an EV battery technician notices damaged structure, they aren’t likely to want to replace the battery in the vehicle. EV battery technicians that aren’t responsible will be selected against by Darwin’s Law. ⚡️🔥💨⚡️
